This study investigated the effects of three doses of spirulina in glucose beverages on postprandial glycemic responses, arterial blood pressure, and subjective satiety.
This study aimed to determine the effects of three different doses (4, 6 and 8 g) of spirulina in glucose beverages on postprandial glycemic responses, blood pressure, and subjective appetite responses in healthy young adults.

Thirteen healthy, with BMI between 18 and 29.9 kg/m2 (male: 3, female:10) after 10-14h fast, consumed 50g glucose diluted in 250ml, tested two times, in different visits, within 5-10min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120min.
Thirteen healthy, with BMI between 18 and 29.9 kg/m2 (male: 3, female:10) after 10-14h fast, consumed 50g glucose and 4g spirulina diluted in 250ml, tested once, within 5-10min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120min.
Thirteen healthy, with BMI between 18 and 29.9 kg/m2 (male: 3, female:10) after 10-14h fast, consumed 50g glucose and 6g spirulina diluted in 250ml, tested once, within 5-10min. Fingertip capillary blood glucose samples were taken at baseline, 15, 30, 45, 60, 90 and 120min.

Capillary blood glucose responses
Clinically useful change in blood glucose, defined as the restoration of glucose within normal limits during 2hr glucose tolerance test
Time frame: 2 hours
Blood pressure
Useful change in systolic and diastolic blood pressure before and 2hr after consumption of the three doses of spirulina in beverages
Time frame: 2 hours
Subjective appetite ratings
Useful change in subjective appetite using visual analogue scales with a score 0 to 10 (given in form of booklet, one scale per page) at baseline, 15, 30, 45, 60, 90 and 120. The minimum or maximum score will be evaluated if it is better or worse depending on the appetite variable e.g. hunger, satiety, desire to eat etc.
Time frame: 2 hours
